  Time to First Byte (TTFB)

  Time to First Byte is 3531 ms (3.53 sec) — Google flags this as "poor" (> 1.8 s per web.dev/articles/ttfb). The browser cannot begin rendering until the first byte arrives, so LCP cannot beat 3.53s. Every downstream Core Web Vital (LCP, INP, CLS) inherits this delay, and Page Experience signals trigger a soft demotion in Google + Bing rankings.

  FAIL · onpage

  Meta Description

  The meta description is missing. Google + Bing + Yandex will fabricate a SERP snippet from random page text — often ending mid-sentence or surfacing irrelevant content. ChatGPT / Claude / Perplexity may quote the description verbatim as a citation snippet; without one, they fall back to less benefit-focused page text. Missing description = lost CTR even when ranking is unchanged.

  Robots.txt

  The robots.txt file was not found at /robots.txt. Without it, Google + Bing + Yandex crawl with default permissions, AI search engines (ChatGPT, Claude, Perplexity, Gemini) may lack explicit policy, and AI training crawlers (GPTBot, CCBot, anthropic-ai, Bytespider) will assume permission to ingest your content silently. A missing robots.txt also means no Sitemap directive, so crawl-budget routing is suboptimal.

  Email Authentication (SPF / DMARC / DKIM)

  SPF: pass · DMARC: fail · DKIM: info. Missing or broken: DMARC. Without SPF/DKIM/DMARC, your emails are likely flagged as spam by Gmail/Outlook, and your domain can be spoofed by phishers.

  Canonical Tag

  The canonical tag is missing. Without <link rel="canonical">, Google + Bing + Yandex may index multiple URL variants of the same content (with/without trailing slash, with tracking parameters like ?utm_source=, http vs https) and split link equity across the duplicates. AI search engines (ChatGPT / Claude / Perplexity) may also cite the wrong URL variant, fragmenting the citation graph for your content.

  XML Sitemap

  The sitemap.xml file was not found at /sitemap.xml. Without a sitemap, Google + Bing + Yandex must rely on internal-link discovery to find your pages — recently published or orphan content may not be indexed for weeks. AI search engines (ChatGPT search via OAI-SearchBot, Claude search, Perplexity) also crawl sitemap.xml to discover content, so missing sitemaps delay AI citation as well.
